passing variable from bash to perl from bash script
Hi Yogesh,
Thanks for your valuable input, and Thanks for reply on it.
I have included the sugeestion , you told me, But When i run it , i am not getting any data, which i want, but the comment from the file.
Here is the Modified Code :
===========================
#!/bin/bash
FROM_DATE="04/05/2008"
TO_DATE="06/05/2008"
perl -ne 'print if ( $_ >= $ENV{'FROM_DATE'} && $_ <= $ENV{'TO_DATE'} )' monitor.audit
exit
=====================================
The output is only the commented line
#Memory Usage
#Check the Availability
#Disk Monitor
#Load Monitor
#Memory Usage
#Check the Availability
The file monitor.audit data
====================

BASHBUG(1) General Commands Manual BASHBUG(1) NAME
bashbug - report a bug in bash SYNOPSIS
bashbug [--version] [--help] [email-address] DESCRIPTION
bashbug is a shell script to help the user compose and mail bug reports concerning bash in a standard format. bashbug invokes the editor specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill in the appropriate fields and exit the editor. bashbug then mails the completed report to bug-bash@gnu.org, or email-address. If the report cannot be mailed, it is saved in the file dead.bashbug in the invoking user's home directory. The bug report format outline consists of several sections. The first section provides information about the machine, operating system, the bash version, and the compilation environment. The second section should be filled in with a description of the bug. The third sec- tion should be a description of how to reproduce the bug. The optional fourth section is for a proposed fix. Fixes are encouraged. ENVIRONMENT
bashbug will utilize the following environment variables if they exist: EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs. HOME Directory in which the failed bug report is saved if the mail fails. TMPDIR Directory in which to create temporary files and directories. SEE ALSO
